Slides version for NFX 2013 Online Release Seminar. This webinar Introduces and demonstrates enhancements of NFX's new updates: such as Mid-Surface Extraction, Implicit Nonlinear Dynamic Analysis, Transient Nonlinear Heat Stress, Optimization.... NFX is a FEA generalist software committing to make your FEA work efficient and cost effective. Go achieve this goal, NFX carries 3 most distinguishable characteristics: 1) CAE/CFD solution-in-one interface: This makes NFX more multidisciplinary, and seriously saves your effort to switch between platforms. 2) Intuitive workflow and GUI: NFX is designed to carry out complicated tasks in headache-free ways. Consistent feedbacks about “fast learning curve” and “junior engineer friendly” make us confident to claim for the best in this one. 3) High-end analysis capacity with affordable price:  provides total solutions from high-end structural analysis functions such as contact analysis, nonlinear analysis, explicit dynamic analysis and fatigue analysis in addition to high-end fluid analysis functions such as moving mesh, free surface analysis and mass transfer analysis.

Stacker Reclaimer Model:
Typical Application: Bulk Material Handling - The
stacking and Reclaiming of Coal/Iron Ore from
material heaps in Bulk Storage Yards
Analysis Intent:
Evaluating the transfer of Conveyor, Gearbox and
Bucket Wheel of an older machine onto a newer
lightweight structure.
FEAApplication :
Evaluate the stress distribution through the structure as the counterweight is slowly being increased to a
point where the existing luffing hydraulics
can accommodate the out of balance portion of the boom and operational payload. Highly stresses areas
will have to be modified/changed.
Different structural solutions can now be evaluated to ensure structural integrity during operations. Once
the needed modifications have been decided on,
